- 1927. Serial My invention relates to change making machines in generaland more particularly to means for conveying coins from the machine to areceptacle. i

It is an object of my invention to provide a discharge and deliverymeans for coin changing and similar machines which is practical inconstruction, reliable and rapid in operation, may be conveniently usedand which may be economically manufactured.

Other objects will appear from the follow ing description, referencebeing'had to the accompanying drawings,'in which Fig. 1 is a frontsectional view of the machine, omitting the majority of the actionelements of the operating mechanism in the lower part of the machine andshowing the interior coin discharging chute of the machine inlongitudinal section;

This application is a division of 1ny copending application, Serial No.718,212, filed June 6, 1924, (Patent'No. 1,673,366, granted June 12,1928) in which the coin tray and other mechanism is specificallyclaimed. 7 The illustrative machine is equipped with a removable cointray 1, compr'isinga row of coin magazines 2, one for each denominationof coin to be ejected. This tray, appearing at the upper front of themachine, is mounted in operative relation to a set of devices 3 forremoving or ejecting coins fromtheimag} 0 azine.

The coin-ejectors 3 maybe operated by appropriate mechanism, such forexample asthat shown-inthe drawings, which is of the general typedisclosed inthe patent toBarrett, No. 1,247,618, dated November 27,1917.

The coins discharged or ejected from the magazines drop upon and ridedown an inclined coin slide 40, and are discharged through an opening41in one of the side walls of the machine casing and'into an ex- SerialNo. 718,212. Divided and this application filed July 23,

'terior delivery chute 50. Said inclined coin 'SllClG 40 constitutes thebottom of an interior discharge chute or receptacle 42, the front wallof which is provided by the front wall of the machine casing. The coinslide 40 1sadvantageously made as a separate sheet metal strip, fittedand secured between the front and back walls of the interior chute orreceptacle '42.

The coin magazines are preferably ar-. ranged with the larger coins tothe right (Fig. 1). This arrangement is advantageous because the heaviercoins, dropping upon the elevated end of the coin slide 40, will slidedown the same and out through the opening 41 at nearly the same time asthe lighter coins drop upon the lower end of the slide; while thelighter coins, having the furthest distance to drop, will therebyacquire such a momentum in proportion to size by the time they strikethe slide as to cause them to travel down theslide and the extension ordelivery chute 50 practically or nearly concurrently A with the heaviercoins.

"To promote reliable and speedy delivery of the coins, the coin-slide 40is formed with a longitudinal channel 46 flanked by shoulders 47, thearrangement being such that the 7 coins can have only two-point contactwith the slide no matter what may be the relation of the coins as theyride down the slide; the width of the channel and of the shoulders 47 orthe distances between the channel and sides'of the interior chute beingless than the diameter of the smallest coins. By the provision of thischannel or trough 46 the coins slide with only two points in contactwith the chute, thus minimizing the friction, especially if the ,chutessurface is, damp, corroded or has accumulated dust. This arrangementthus promotes speedy delivery of the coins and overcomes thetendency ofthe coins to be retarded or stopped by the effect of dust accumulation,rust or the like.

Theexterior delivery chute 50, forming a continuation of the interiorChute, is shown inclined downwardly and curved laterally toward the backof the machine for delivering the coins to a position convenient to thecustomer or recipient of the change (Figs. 1, 1 0

2 and 3). At the delivery end of the chute is a barrier 51 to arrest thetravel of the coins and cause them to drop through the opening 52. Thechute is shown as of substantial right-angular cross section, with thebottom thereof of the same form and character as the interior coin slide40, said bottom of the chute being formed with the channel 53 flanked bythe shoulders 54 (Figs. 4, 5 and 6). This formation, enabling the coinsto ride down the chute 50 on two-point bearings, minimizes friction andthe retarding effect of dust, corrosion or the like, thus promotingspeedy delivery as already explained. On the other hand, the gradualdeflectionof the travel of the coins incident'to the curvature of thechute 5O exerts a desirable retarding influence. Furthermore, theinclination of the chute decreases toward its delivery end, as appearsmore clearly in Fig. 3, tending to check the velocity of the coins. Bythe time the coins reach the delivery end of the chute, they will bemoving in such manner and at such rate as to insure dropping through theopening 52 or striking against the barrier 51 and drop ping into saidopening without over-shooting or undesirable rebounding.

The'coins are deposited in a cup 55. The bowl of this cup may be.pear-shaped in plan View, as shown in Fig. 2, and semi-pear-shaped inlongitudinal section, as shown in Fig. 8. This formation provides a maincup portion or concavity 56 with a tapering chute-like ex-. tension 57,having an inclined bottommerging into the bottom of the deeper portionor main concavity of the cup. The cup is disposed with its chute-likeextension 57 under the discharge opening 52 in the de livery end of thechute 50, there being only a slight distance between said opening andthe bottom of said cup extension 57 so that the coins delivered by thechute 50 have a short drop into the cup. The said cup extension 57serves as an auxiliary chute down which the coins slide into the maindeeper portion or recess 56 of the cup, from which they may beconveniently removed by the customer or recipient of the changedelivered from the machine, said deeper portion of the cup being shapedto permit picking up the assembled coins by the fingers.

The travel of the coins ejected from the magazines of the machine by thechangemaking operation may be considered as comprising three steps, ahiglrspeed step on the coin slide 40, a second step in the extensionchute 50 at relatively high-speed until the coin is arrested by the coinbarrier 51 at the delivery end of the chute, and then a relatively slowspeed of travel from the rear higher end to the front deeper end of thecup to effect the depositing of the coins at the ultimate terminuswithout danger of throwing them out.

The cup 55 is shown formed integrally with a peripheral wall 58 havingears 59 by which the cup is attached to a sheet metal base plate 60, thelatter being attached to the bottom plate 61 of the machine casing asindicated at 62 in Figs. 2 and 3. The coin chute 50 may i be formed as asheet metal stamping having its inlet end formed with a flange 63 forattachment to the side wall 64 of the machine casing by screws 65 or thelike as shown in Figs. 1 and 2.

The several improvements described promote reliability of operation inthe delivery of successive batches of change tocustomers during more orless frequent repeated operations of the machine; contribute to the production of a machine of convenient character; and provide a practicablestructure susceptible of economical manufacture.

.1. In a machine of the class described, an

interiorcoin chute arranged to effect a rapid and substantiallyconcurrent discharge of coins of different denominations simultaneouslyplaced upon difierent portions thereof, said chute being formed with apair of'longitudinally extending shoulders to provide a two-pointcontact with the coins as they slide down the chute, and having adownwardly inclined curved extension portion having at its delivery endan integral barrier and opening in front of said barrier into which thecoins may drop.

2. In a machine of the class described, a chute for the rapid deliveryof coins from a coin-ejecting mechanism, said chute comprising a steepdownwardly inclined portion, and a portion of lesser downwardinclination, each of said portions being channel-shaped in cross sectionand having a trough with inclined sides formed in the bottom of saidchannel.

3. In a machine of the class described, a chute for the rapid deliveryof coins from a coin-ejecting mechanism to a receptacle, said chutecomprising a downwardly inclined continuous channel-shaped trough havinga depressed portion extending longitudinally thereof, the width of thebottom of the depressed portion being less than the diameter for thedelivery of coins, comprising an upper rectilinear portion of relativelysteep slope, and a lower arcuate portion of lesser slope, each of saidportion's being substantially} U-shaped in cross section and havinglongitudinally extending shoulders at each side of their bottomsurfaces.

In Witness whereof, I hereunto subscribe my name this 19th day of July,1927.
